Galaxy RHT
What is Galaxy RHT?
RHT (Radiant High Temperature) heaters are infrared pre-mix gas systems that reach radiant surface temperatures of up to 950°C. They deliver a safe, reliable source of process heat by burning natural gas or propane and transmitting the energy as short-wavelength infrared radiation. Because that energy is absorbed directly by the exposed material, heating is fast and uniform — ideal for high-temperature processes such as dry-off, pre-gel, mould pre-heating and powder melting.
It works by:
- Preparing a calibrated air/gas pre-mix in each burner’s integrated control system
- Burning that mixture as a stable microflame across a metal-fibre radiant surface
- Re-radiating the heat as short-wavelength infrared, absorbed directly and evenly by the target
Radiant High Temperature Technology
RHT radiant heaters deliver safe, reliable heat via short-wavelength infrared rays from gas combustion (Natural Gas or Propane). Infrared energy is absorbed rapidly and evenly by exposed materials, making the units ideal for high-temperature processes such as dry-off and pre-gel. They can be used alongside Gas Catalytic IR heaters or entirely on their own.
Every unit is constructed from high-temperature-rated stainless steel, with each burner featuring a precision pre-mix system for a consistently calibrated air-to-gas ratio.
This results in:
♦ Low-cost, standalone, independent units
♦ Optional remote PLC control for automation
♦ Rapid heat-up with ultra-low NOₓ emissions
♦ Complete, RHT units, ready to install
Why Use RHT Radiant Heat?
Fast, Uniform Heating
Infrared energy is absorbed directly by the material rather than the surrounding air, so parts reach temperature quickly and evenly.
This results in:
♦ Rapid heat-up and short cycle times
♦ Even absorption across the surfaces
♦ Minimal airflow, reduced part movement
Flexible Install & Control
Each RHT unit ships as a complete assembly and modulates continuously, so it drops into new or existing lines with minimal complexity.
Allowing:
♦ Continuous 50%–100% power modulation
♦ Standing-alone or remotized PLC control
♦ Compact, ready-to-install units
improved final coating quality
A WolfRayet Galaxy Boost pre-gel oven can improve the quality of the final product. The improved flow and adhesion of the powder coating material result in a more even and uniform finish, with no cross-contamination between parts.
Achieve:
♦ Smooth, even coatings
♦ No cross-contamination between parts
♦ Durable, long-lasting performance
